Padlock System Series
General Information

System Series padlocks are designed to be keyed alike and master keyed with most existing Medeco high security door hardware keying systems. The 54-X1 series offers superior weather resistance and the 54-X2 series offers excellent protection against bolt cutters.


Laminated steel body provides strength and protection against forced attacks.
Boron alloy steel shackle resists up to 15,000 lbs. of pressure from bolt cutter attacks.
Boron alloy steel shackle provides increased tensile strength and dual ball bearing locking design resists forcing of the shackle.
Xenoy thermoplastic cover on padlock body protects it from dirt and adverse weather conditions.
Steel retainer screw and hardened steel cylinder retainer provide protection against dent puller attacks.
Drainage channels allow water to flow through the padlock rather than getting trapped inside and freezing during cold weather.
Utility patented key control, (for cylinders that incorporate the Biaxial design), provides protection against the unauthorized duplication of keys.
A special elevating and rotating pin tumbler design, along with false slots on the bottom pins, mushroom top pins and a sidebar mechanism, work together, to provide superior pick resistance.
Angled cuts on the keys, along with fore and aft positioning, in the Biaxial design, provide added dimensions that dramatically increases key combinations and enables Medeco to produce some of the largest master key systems in the industry.
Hardened steel inserts, positioned in critical areas of the cylinder, provide a high degree of drill resistance.
UL437 listing provides assurance that cylinders meet universal standards for drill and pick resistance and resistance against other types of forced attack.
54-X1 series padlocks have polyurethane material around the shackle to help prevent water and dirt from entering the shackle holes. In addition, a dust cover protects the keyway from water and dirt.
54-X2 series padlocks have a shrouded shackle guard to provide additional resistance against bolt cutter attacks.
